Every week, Mrs Jeremy collected 60% more vitamin pills than Mrs David from the pharmacy. They each consumed 14 vitamins weekly and would leave the rest for their family members to consume the rest. After some time, both ladies consumed a total of 224 vitamin pills and Mrs Jeremy's family members consumed 840 more vitamin pills than Mrs David's family.

1. How many members were there in Mrs Jeremy's family, if they each consumed 14 pills weekly?
2. How many vitamin pills did Mrs David collect from the pharmacy each week?

(a)
60% + 100% = 160%
160% = ¹⁶⁰₁₀₀ = ⁸₅

Number of pills Mrs David collected in total = 5 u
Number of pills Mrs Jeremy collected in total = 8 u

Total pills eaten per week by Mrs David and Mrs Jeremy
= 14 + 14
= 28

Number of weeks
= 224 ÷ 28
= 8

Difference in the number of pills Mrs Jeremy's family consumed more than Mrs David's family
= 8 u - 5 u
= 3 u

3 u = 840

1 u = 840 ÷ 3 = 280

Number of pills that Mrs Jeremy collected in total
= 8 u
= 8 x 280
= 2240

Number of pills that Mrs Jeremy's family consumed per week
= 2240 ÷ 8
= 280

Number of members in Mrs Jeremy's family
= 280 ÷ 14
= 20

(b)
Number of pills that Mrs David collected in total
= 5 u
= 5 x 280
= 1400

Number of pills that Mrs David collected each week
= 1400 ÷ 8
= 175

Answer(s): (a) 20; (b) 175
